Embodiment 1

[0085] Such as figure 1 As shown, the embodiment of the present invention provides a method for drawing a three-dimensional intersection enlarged map, including:

[0086] Step 101: Obtain the coordinates and lane direction of the intersection to be drawn, and determine an intersection area of ​​a preset size according to the acquired coordinates and lane direction, and the intersection area includes the intersection to be drawn;

[0087] Step 102: Obtain the background information in the intersection area, and draw the background in the background sub-area in the drawing area according to the background information;

[0088] Step 103: Obtain the road information of the intersection area and the road where the intersection to be drawn is located, draw a three-dimensional road model in the road sub-area of ​​the drawing area according to the road information, and form an enlarged three-dimensional intersection map of the intersection to be drawn.

[0089] In the embodiment of t...

Embodiment 2

[0091] An embodiment of the present invention provides a method for drawing a three-dimensional intersection enlarged map. Among them, in the basic navigation data of the national highway, there are information such as the coordinates of the intersection included in the national highway, the background information of the area near the intersection, the road information and / or road signs of the intersection, and the background information includes at least the information in the area near the intersection. The type and area of ​​the planar background may also include the type of point background included in the vicinity of the intersection, and the road information of the intersection includes lane direction, number of lanes, road shape and / or road geometry, etc.

[0092] Among them, in the embodiment of the present invention, the intersections included in the national highways are sequentially acquired from the basic navigation data of the national highways. Whenever an interse...

Abstract

The invention discloses a method and a device for drawing a three-dimensional enlarged intersection image and belongs to the field of computers. The method comprises the following steps: acquiring the coordinates and the lane direction of an intersection to be drawn and determining an intersection region of a preset size according to the coordinates and the lane direction, wherein the intersection region includes the intersection to be drawn; acquiring background information of the intersection region and drawing a background in a background sub region of a drawing region according to the background information; and acquiring road information about the intersection region and a road where the intersection to be drawn is located and drawing a three-dimensional road model in a road sub region of the drawing region according to the road information to form a three-dimensional enlarged intersection image of the intersection to be drawn. The device comprises a determining module, a first drawing module and a second drawing module. With the method and the device of the invention, the speed and the efficiency for drawing a three-dimensional enlarged intersection image can be improved.

Description

technical field [0001] The invention relates to the field of computers, in particular to a method and device for drawing a three-dimensional intersection enlarged map. Background technique [0002] With the rapid development of science and technology, navigation products are playing an increasingly important role in daily life. In order to make navigation products more refined, humanized and personalized, when arriving at a highway intersection, the navigation products can provide the The three-dimensional intersection corresponding to the intersection enlarged map. [0003] Wherein, the three-dimensional intersection enlarged map corresponding to each intersection included in the national highway is stored in the navigation product, and the three-dimensional intersection enlarged map corresponding to each intersection included in the national highway is manually drawn by the technician in advance using image editing software; When there is an intersection, the navigation p...
